Bug ID: 427776
Summary: Plasma crashed after click in "Show Desktop" mode
Product: plasmashell
Version: 5.18.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: k...@xapienz.ru
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.18.5)
Qt Version: 5.14.2
Frameworks Version: 5.73.0
Operating System: Linux 5.8.14-200.fc32.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 32 (Thirty Two)"
-- Information about the crash:
- What I was doing when the application crashed:
"Show Desktop" (Meta+D / Ctrl+F12) mode was opened after some random keyboard
pressures (by the cat).
I tried to press Esc to close it, but it didn't react. Then I clicked in the
middle of desktop with the mouse, and it crashed.
Cannot reproduce it by doing same things again.
The crash does not seem to be reproducible.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
